tests: Make parallel-vm.py log easier to use for debugging failures

Print a list of full paths to log files from failed test cases both the
parallel.log and stdout so that they can be easily opened for analysis.
In addition, renumber the VM lines in the <timestamp>-parallel.log to
match the i+1 numbering used in the log directories and UI that is
tracking test execution.
